Cop photo goes viral: Boston policeman delivers milk during lockdown

During the manhunt for Dzhokhar Tsarnaev and Boston's lockdown, a Watertown resident snapped a photo of a cop delivering milk to a family with young children.

The image, with tens of thousands of Facebook shares and retweets, is of an officer from the Brookline Police Department, CBS Boston reports.

It's unclear who took the photograph, but it appears to be from inside the home where the officer delivered the milk.
